Slow Pitch DeMarini Softball Bats are among the most dominant bats for softball. Ray DeMarini started building and selling softball bats out of his garage, and while they now have a state of the art facility making DeMarini bats just outside of Portland, Oregon, DeMarini's insane dedication to performance is still present in the building. DeMarini is one of the few bat makers that has a full team of softball bat engineers designing and testing bats. Constant development of high end composite and aluminum materials help make DeMarini softball bats one of the best choices for a day at the field.
